It is far more plausible that this was a "challenge" someone made, to see how long it would take to be solved - I have found many such transactions. I doubt that a weak PRNG is the cause of this key, but it being a collision with a properly generated key is so unlikely that we can safely assume that is not what happened. Even if it were, it's not really any cause for concern. Managing to crack a single key via collision by absurd luck is not going to be repeatable.
A few keys I've found:
